Arizona greets the morning under a clear, pale sky as cool air lingers across the Valley. Breath shows briefly at sunrise, but sunlight already hints at a quick turnaround by afternoon.

According to the National Weather Service in Phoenix, dry conditions remain locked in across central Arizona with a steady warming trend developing through midweek. Morning lows start in the low 40s, then climb sharply under abundant sunshine. No rain or wind hazards are expected, but the daily temperature swing will be noticeable.

In Phoenix, early temperatures sit in the upper 40s before rising into the upper 60s today. Skies stay mostly sunny, and light winds keep conditions calm. By Tuesday and Wednesday, highs push into the low to mid-70s, creating springlike afternoons despite cool overnight lows near 50. The dry air allows heat to escape quickly after sunset, setting up crisp evenings.

Drivers won’t face winter hazards, but early commuters should expect cooler cabin temperatures at sunrise. Outdoor plans benefit from the sunshine, though layered clothing helps manage the morning-to-afternoon contrast. Hikers should bring water, as dry air accelerates dehydration even in mild weather.

Midweek warmth peaks Wednesday and Thursday with highs near the mid-70s. Friday stays warm and dry, continuing the quiet pattern. Looking ahead, 6–10 day outlooks suggest precipitation chances remain low while above-normal temperatures spread across the Southwest into early February. For now, winter steps aside without a stormy exit.

Enjoy the sunshine, but plan for chilly starts and warm finishes. Feeling the temperature swing where you are this morning?
